Let's undo some cables!

Disconnect the ribbon from the ZIF (Zero Insertion Force) connector by flipping up the small black flap with a spudger or fingernail and removing the cable using the blue tab to pull away.

Undo both bundled cable connectors by pulling collectively on the wires and helping it along with a spudger to disconnect.

Once the cables are disconnected, unthread the cables from their grooved paths in the upper housing.
